These are 2015's 10 biggest songs, according to Instagram

What songs were on Instagram users' minds — and in their captions — in 2015?

New year-end data from Instagram identifies the ten buzzworthy songs on the photo-sharing app this year, ranking Billboard's top charting songs by their mentions in captions or comments.

Expect to see Hello, and multiple Taylor Swift songs, on the list. And apologies to the songs that just barely missed the top 10: Demi Lovato's Cool for the Summer and Drake's oft-meme'd Hotline Bling.

10. 100, The Game feat. Drake

9. Thinking Out Loud, Ed Sheeran

Sheeran's heartstrings-tugging ballad seems made to quote in sappy Instagram comments.

8. Worth It, Fifth Harmony

IG users loved Fifth Harmony's girl-squad anthem this year.

7. Focus, Ariana Grande

Grande's comeback anthem has empowering lyrics tailor-made for inspiring photo captions.

6. Bad Blood, Taylor Swift

Taylor Swift had an enormous year, notching two songs in the top 10.

5. Blank Space, Taylor Swift

Let's hope not too many friendships were crushed or hearts were broken with a Swift-quoting Instagram comment this year.

4. She's Kinda Hot, 5 Seconds of Summer

The Aussie pop punk band claims a huge, obsessed fandom.

3. Hello, Adele

With how ubiquitous "hello from the other siiiiide" has become in such a short amont of time, it's amazing this song didn't claim the top spot.

2. Good For You, Selena Gomez

Impressive! Coming ahead of Adele and T-Swift is Selena Gomez' steamy summer single.

And the number one spot goes to...

1. What Do You Mean, Justin Bieber

Bieber bested his ex Gomez for the top spot on Instagram's list, which named his comeback single the buzziest song of 2015.
